WASH BASIN Filed Nov. 9, 1956 2 Sheets-Sheet 1 INVENTOR. Jzlims i/izrwifi ATTOR/YE'Y United States Patent G WASH BASIN Julius Hurwitz, Eayside, N. Y. Application November 9, 1956, Serial No. 621,386 3 Cla-ims. (Cl. 4-166) This invention relates to an improved construction for a wash basin, such as an ordinary bathroom basin. More particularly, the invention has reference to an improved means for supporting a basin of this type upon a marble ledge or other flat-surfaced, plate-like support.

Heretofore, it has been the practice to attach a wash basin to the underside of the plate-like support, through the use of bolts, screws or equivalent fastening elements. conventionally, the basin has an outwardly directed peripheral flange, formed with spaced openings adapted to receive bolts extending upwardly through the openings, said bolts being engaged in the underside of the marble support plate.

This arrangement has certain notable disadvantages. One of the disadvantages of the construction presently employed resides in the fact that it is necessary to drill and tap the marble plate, which is a relatively expensive operation that must be carried out with considerable skill toinsure that the bolts will be properly located.

Another deficiency is found in the present arrangement, in that crevices are defined, opening onto the interior of the wash basin. These not only provide spaces in which dirt lodges, rendering cleaning ditficult and producing an unsanitary condition, but also causes the overall efiect to be somewhat unattractive. It may be noted that reference is here made to the particular type of arrangement in which the basin is carried by a marble support plate. This arrangement is finding renewed favor in modern constructions. I

In accordance with the invention, the wash basin has an outwardly directed flange, so designed that the basin may be merely positioned downwardly through the basinreceiving opening of the marble support plate. When the basin is so inserted, the flange at its underside seats upon the top surface of the support plate, so that the basin is properly supported without the requirement of screws, special fastening elements, drilling of the marble plate, etc. Further, crevices opening onto the inside of the basin are completely eliminated, the water-receiving container portion of the basin being wholly smoothsurfaced except, of course, for the provision of the usual drain and overflow openings.

One object of importance is to provide a generally improved basin construction for mounting in the openings of marble support plates, that will permit the installation to be carried out with maximum speed and ease.

Another object is to so design the wash basin as to eliminate the necessity of exact proportioning and determining of the basin-receiving aperture of the support plate or ledge.

A further object is to provide a basin construction as stated which, despite its having the above described advantages as compared to the conventional basins heretofore designed, will nevertheless be capable of manufacture at no greater cost than said conventional basins.

Stillanother object is to design the basin in such a manner that a novelly shaped sealing gasket, interposed between the support flange and the marble plate, will "ice serve efliciently to provide a leaktight engagement of the basin against the support plate, with the sealing action deriving from the weight of the basin imposed upon the sealing gasket.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

in the accompanying drawings forming a material part of this disclosure:

Fig. 10 is a view like Fig. 9 in which the wash basin has moved downwardly beyond the position of Fig. 9 to partly compress the gasket, but has not reached its fully seated position shown in Fig. 7.

Fig. ll is a view similar to Fig. 8 showing another modification.

Fig. 12 is a view similar to Fig. 11 in which the modified form shown in Fig. 11 has been illustrated in its fully seated position.

Referring to the drawings in detail, in the several figures of tl e drawing a marble basin stand has been shown, said stand including a marble support plate it: supported upon legs 12 against wall, with towel racks 14 extending between the legs at opposite sides of the stand.

The support plate 16 is formed with a center opening 16 which in the illustrated example is of circular configuration. However, the center opening, and the basin 1%? seating herein, can be of various other shapes, as for example oval, rectangular, etc.

In any event, the wash basin 18 constituting the present invention includes a depressed body portion 20, which can be provided at a selected level above the bottom thereof with an overflow opening 22 communicating with the upper end of an overflow drain 2% integrally formed upon the body. Drain 24 terminates below the center of the body portion, and is in communication at the center of the basin with a drainpipe 26. The body portion is formed with a centrally disposed main drain opening, normally covered by a stopper 28 (see Fig. 5).

The body portion 2-5} is formed with downward projections'Zil to facilitate the manufacture of the same.

In accordance with the present invent-ion, the body portion 20 at its periphery is formed with an outwardly projected flange 3t adapted to seat upon the support plate ill. The outer periphery of the flange 30 is substantially greater in diameter than the diameter of the opening 16,

the flange. a downwardly opening approximately semicircular'shape of the support 'l-ationship to the .marbl u 7 r positioned through the opening ar against the plate 1 and will so that when the basin is 16, the flange 30 will be i hold the basin in supported position within the support plate 16,

the body portion 20. The flange 30 is arcuately bowed upwardly when viewed in cross section, through substan tially 180 of a circle, thus defining on the underside of groove 32 extending substantially the full width ofthe flange and having an when seen in cross section, asshown to best advantage in Fig.3. 7 V

The wall of the groove 32, at the inner side of the groove, merges smoothly into'the outer surface of the body portion 20, and said outer surface of the body portion as shown in Fig.3 is spaced inwardly from the wall of the support plate opening 16.

Disposed within the downwardly facing groove 32 is a gasket 36,. for-med of soft rubber or other resiliently compressible, leak-preventive material. The gasket 36, in its normal, uncompressed condition shown in Fig. 4, is of semicircular cross section, said gasket extending continuously through the full circumference of the wash basin.

Preferably the gasket 36, at its point of greatest height, is slightly thicker than the maximum depth of the groove 32 as shown in Fig. 4. Accordingly, when the basin is inserted through the opening 16, the flange 30, as it comes to bear against the gasket 36, will begin to compress the gasket. The gasket is freed to be deformed into the opening 16, that is, the inner peripheral portion 38 which normally has a bottom surface coplanar with the top surface of forced downwardly into the opening 16 to a slight extent, asshown in Fig. 3, so that said inner peripheral portion becomesa spacer between the wall of the opening 16 and the outer surface 34 of the body portion 20.

By reason of this arrangement, the gasket becomes a centering device, which insures that the ba centered within the opening 16 throughout of contact with the wall of said opening. Further, the basin is held against movement out of concentric relationship to the opening 16, due to the deformation of the inner peripheral portion 38 of the gasket into the opening 16 between the walls of the body portion 20 and of the opening 16.

The gasket can initially be cemented to the top surface plate, before the basin is inserted in position within the gasket, thus to temporarily hold the gasket properly centered, as the basin moves into its finally seated position.

sin is properly It is important to note that the gasket is compressed by reason of the weight of the basin, and further, the

weight of the basin maintains the basin Within the opening 16, without the requirement of any special fastening elements. 1

' The inner surface of the body portion 20 can be left smooth as shown, or alternatively, can 'be suitably shaped, either for utilitarian or for ornamental purposes. For example, it may be desired that the interior of the basin be formed with spiralling corrugations, so as to impart a swirling motion to the Wateras it flows into the basin. This is believed sufliciently obvious as not to require special illustration herein, and of course, does not constitute the invention. The invention resides in the particular manner in which the wash basin is formed in regasket, for seatingof the wash basin merely by insertion through 'thejopening of the wash-stand, with the basin thereafter remaining in proper position without the requirement of screws or the like. L.

the support plate 10, is caused to be deformed or e stand and to a compressible der 42.

In Fig. 6 there is shown a modified construction wherein the basin 1=8 hasa peripheral flange 30 on its'body portion 20, said flange being of approximately semicircural cross section but being solidly formed, except for the provision of a downwardly facing groove 32* in its underside, the side walls of which are spaced inwardly substantial distances from the flange. this form of the invention, and is compressible gasket 36*.

fThe gasket 36 can be cemented within the groove 32 as shown in. Fig. 8, or alterna-tively, may be lightly The gasket 36 has a top surface which is of a width equal to the widthof the groove 32, and in its normal, uncompressed condition the gasket is slightly thicker than the depth of the groove as shown both in Figs. 8 and 9. The side walls 40 of the gasket, in the uncompressed condition of the gasket, converge downwardly when the gasket is viewed in cross section with the gasket being substantially narrower at its bottom than the width of the groove 32 With the gasket seated in the groove 32 the basin is adapted to receive a lowered into the opening 16 as shown in Fig. 8. Then,

when the gasket initially contacts the top surface of the support plate 10, the gasket will still be in its original shape shown in Figs. 8 and 9.

' The weight of the wash basin 18 will now cause thewash basin to sink lower within the opening 16, to the Fig. 10 position, and this causes thegasket to be compressed in a vertical direction, viewing the same as in. 'Figs. 9 and. 10, causing the gasket to expand 'widthwise. The side wallswill now move into cont-act with the side walls of the groove 32 and in Fig. 10; are shown deformed outwardly, though not completely. filling the groove 32*. Ultimately, when the washbasin is fully seated with the underside with the top surface of will have been fully compressed, so as to now have a rectangular cross section, completely filling the groove 32 in the manner shown in Fig. 7. A tight seal is thus,

etfected between the wash basin'and the washstand, re-L sulting entirely from compression of the gasket caused by the continuous downward pressure exerted thereon by the weight of the washstand.

In Figs. 11 and 12, there is shown another modification wherein the basin 13 has an outwardly directed peripheral flange 30 'forrninga wide, relatively'shallow groove 32 of approximately rectangular cross section. The basin is formed in this instance with a shoulder 'at the inner side of thejgroove 32 and initially, the gasket 36 is of a width substantially equal to the distance, in a direction radially of the basin, between the outer side wall of the groove 32 and the inner edge of the shoul- When the basin is lowered into the opening 16, the shoulder 42 will deform the inner peripheral portion 38 of the gasket, so as to force the same downwardly in' a manner to offset the inner peripheral portion 38 downwardly from the outer periphery of the gasket, into. the

opening 16. As a result, the compressed gasket shown in Fig. 12 causes the basin 18 to be fully centered within. the opening 16, while at fective seal about the basin and extending, in eflect, as a locking means between the basin and the support plate 10. I w
